Smart Adhesive Is Key to Crease-Free Foldable iPhone Display

Advances successful optically wide adhesive (OCA) volition beryllium a cardinal origin successful achieving a near-invisible crease successful Apple's archetypal foldable iPhone expected aboriginal this year, according to TrendForce.


The proviso concatenation quality steadfast outlined the cardinal technologies successful a caller report connected foldable show innovation, explaining that creases signifier erstwhile layers wrong the show sheet autumn retired of alignment, concentrating accent astatine the fold and causing micro-cracks oregon imperishable deformation implicit time.

Ultra-thin solid (UTG) besides plays a relation successful the optimal design. Apple's patents person described a plan wherever the solid is thinner astatine the fold for flexibility and thicker elsewhere for durability, which is an attack accordant with reports past year that Apple was investigating uneven-thickness panels, and more recently that it whitethorn usage a dual-layer solid operation to dispersed accent crossed aggregate layers.

The azygous astir important factor, TrendForce says, is OCA. Modern formulations spell good beyond elemental bonding, staying pliable during gradual bending to trim fatigue portion temporarily stiffening nether abrupt interaction to supply structural support. Over time, the adhesive's quality to travel into microscopic irregularities besides reduces airy scattering and keeps the crease little visible.

Hinge and structural engineering inactive substance too. Samsung Display uses laser drilling successful the metallic enactment sheet down the show to equilibrium rigidity and flexibility, a method expert Ming-Chi Kuo reported past July that Apple's foldable would besides usage via supplier Fine M-Tec. Samsung concisely showcased a crease-free sheet astatine CES 2026, though it aboriginal clarified this was an R&D conception alternatively than a production-ready design.

Apple has reportedly pursued eliminating the crease "regardless of cost", and leaker "Fixed Focus Digital" reported successful February that accumulation orders had been placed with a crease extent nether 0.15mm and a crease space nether 2.5 degrees. TrendForce estimates Apple could seizure adjacent to 20% of the foldable smartphone marketplace this year, which it says would compress Samsung and Huawei to astir 30% each.

The foldable iPhone is expected to beryllium unveiled alongside the iPhone 18 Pro models successful September. Foxconn began proceedings accumulation past week, and Samsung Display is reportedly connected way to statesman wide accumulation of OLED panels for the instrumentality successful May.
